That was the peak of the UFC as far as I'm concerned.
I don't think any card today can top it for various reasons. You only have to look at what Brock, GSP and Bisping have earnt in the UFC to understand how big a draw they all are. 3 of the top draws in the company's history.
Brock Lesnar's PPV power was ridiculous, he was a one off.
GSP was proably at his peak then in terms of marketability, and he's always been one of the very best draws. I recall Dana White saying he's the biggest star they have.
And Bisping, like it or not is a big seller. And it was a big grudge match off the back off TUF and the whole of the US wanted to see him get KOd.
I reckon Anderson Silva is probably the biggest draw at the moment because everyone wants to see if he will come back like a mad man following the loss, but I'm not convinced enough people care about Jones or any of the other champions enough for a bigger buy rate than UFC 100.
They'd need at least 3 title fights. Even then I'm not convinced they'd beat it.
